spi oddities

hi:

i'm converting some tried and true hc11 code on a b32. already been through d7 issue as discussed earlier. i have a slow LCD spi peripheral (64kbit speed) that can only be written every 500ms. moving the code over to the hc12b32 i am experiencing intermittent write failures. is there something i'm not aware of that is fundamentally different between the two processors? thanks in advance ed




If you are not using SSOE, make it an output. Give that a try.
